yellow hyaline colour; nervures black except on the lighter parts 

 of the wings, where they are yellowish; hindwings iridescent 

 hyaline. 



The whole insect is covered with fine punctures except a small 

 round spot, which is quite smooth, situated on each side of the 

 upper surface of the first abdominal segment, near its base. 

 Head almost hemispherical, a little broader than long viewed 

 from above; fovea forming a raised ridge or horse-shoe-shaped 

 mark on summit of head; labrum rugose, flattened; jaws short; 

 antennae hidden at base, composed of the usual ten joints in the 

 female, being very irregular and variable in form, the terminal 

 one very slender. Thorax rounded in front; pronotum forming 

 a regular collar; front of mesonotum slightly keeled in centre, 

 slightly constricted behind at junction with abdomen. Legs 

 stout; tibiae of hind legs dilated and serrate along upper margin, 

 terminated with a single spine at apex; fore tarsi three-jointed, 

 middle and hind tarsi five-jointed, the penultimate joint in all 

 being the smallest and not always easy to distinguish. Ovipositor 

 slender, spine-shaped, exserted in one specimen but not visible 

 externally in the other. 



Mackay, Q.; in March and August. 



Described from two specimens, one being considerably worn 

 and showing only traces of the pile on the body. 



The specimen taken in August last year was found on a gum 

 fence post and I captured it easily in my fingers; the other was 

 caught by my brother in a net on a fallen log in the scrub where 

 each of us afterwards on different occasions saw another which 

 unfortunately we failed to secure. On attempting to capture it 

 in my fingers it ran quickty along the log for a short distance 

 and on being approached closely it took to the wing, first making 

 a jump off the log, in a manner similar to that of manj 1 - Chalcids; 

 it again alighted on the log and I then tried to catch it in the 

 net but only succeeded in frightening it away, and never saw it 

 again.
